""A cranberry juice extract (CJE), rich in proanthocyanidins, had weak prooxidant properties, generating low levels of hydrogen peroxide (H2O2) and superoxide. Generation of H2O2 was pH dependent, increasing at alkaline pH, and was lowered in the presence of catalase and, to a lesser extent, of superoxide dismutase (SOD). Growth inhibition and cytotoxicity were noted towards human oral carcinoma HSC-2 cells, with midpoint cytotoxicity at 200??g/mL CJE, but not towards human gingival HF-1 fibroblasts. http://www.selleckchem.com/products/Rapamycin.html Being a mild prooxidant, CJE toxicity was unaffected by exogenous catalase and pyruvate, scavengers of H2O2, but triggered intracellular synthesis of reduced glutathione, as confirmed by cell staining with Cell Tracker? Green. The presence of exogenous SOD potentiated the toxicity of CJE, possibly by stabilizing the CJE phenols and hindering their degradative autooxidation. Conversely, ��spent�� CJE, i.e. CJE added to cell culture medium and incubated for 24?h at 37?��C prior to use, was much less toxic to HSC-2 cells than was freshly prepared CJE. These differences in toxicity between SOD-stabilized CJE, freshly prepared CJE, and ��spent�� CJE were confirmed in HSC-2 cells stained with aceto-orcein, which also indicated that the mode of cell death http://www.selleck.cn/products/PD-98059.html was by the induction of apoptosis.

""Shuang-Huang-Lian (SHL), a famous traditional Chinese medicine recipe containing Lonicerae Japonicae Flos (LJF), Forsythiae Fructus, and Scutellariae Radix, is clinically used for the treatment of fever and acute upper respiratory tract infection. In this research, a comparative study was conducted to compare the pharmacokinetic difference of chlorogenic acid (ChA) after oral administration of LJF and SHL to normal and febrile rats with approximately the same dose of 60?mg/kg, and the antipyrexia effect of LJF and SHL on rectal temperature changes induced by Baker's yeast was investigated. The results indicated that AUC0???t and plasma concentrations of ChA in the febrile rats were significantly higher than normal rats whether in the extract of LJF or SHL. In addition, SHL increased the values of AUC of ChA in both febrile and normal rats compared with LJF alone (p?
